Speaking of jazz classics, I just saw a press release reminding me that it has been 50 years since Paul Gonsalves’ six minute solo on “Diminuendo and Crescendo In Blue” brought the proverbial house down at the Newport Jazz Festival.

Tonight, on the radio, Columbia record producer George Avakian, Newport Jazz impresario George Wein, and critic Stanley Crouch will be savoring the memory of Duke Ellington and His Orchestra’s historic performance — the program is Open Source, it airs from Boston (89.7 on the dial) at 7 PM and can be heard online here.
